A new approach to active noise and vibration control - [Part I: the known frequency case]
PublikacjaThis paper presents a new approach to rejection of complex-valued sinusoidal disturbances acting at the output of a discrete-time stable linear plant with unknown dynamics. It is assumed that the frequency of the sinusoidal disturbance is known, and that the output signal is contaminated with wideband measurement noise. The disturbance rejection control rule is first derived and analyzed for a nominal plant model, different from...

Wpływ ascenzji wód piętra kredowego na jakość wód plejstoceńskiego poziomu wodonośnego w zachodniej części Żuław Gdańskich = The influence of ascent from cretaceous to pleistocene aquifer on the groundwater quality in the western part of Vistula River Delta
PublikacjaZachodnia część delty Wisły jest regionem zasobnym w wody podziemne. Występują one w utworach kredy górnej i plejstocenu. Szczególnie korzystne warunki hydrogeologiczne występują w pogrzebanej dolinie wypełnionej piaskami i żwirami, przebiegającej wzdłuż zachodniej granicy Żuław Gdańskich. W zasilaniu plejstoceńskiego poziomu wodonośnego w tym rejonie znaczący udział ma ascenzja wód z pietra kredowego. Udział ten zaznacza się...

Existence and uniqueness of solutions for single-population McKendrick-von Foerster models with renewal
PublikacjaWe study a McKendrick-von Foerster type equation with renewal. This model is represented by a single equation which describes one species which produces young individuals. The renewal condition is linear but takes into account some history of the population. This model addresses nonlocal interactions between individuals structured by age. The vast majority of size-structured models are also treatable. Our model generalizes a number...

Comparison of anti-plane surface waves in strain-gradient materials and materials with surface stresses
PublikacjaHere we discuss the similarities and differences in anti-plane surface wave propagation in an elastic half-space within the framework of the theories of Gurtin–Murdoch surface elasticity and Toupin–Mindlin strain-gradient elasticity. The qualitative behaviour of the dispersion curves and the decay of the obtained solutions are quite similar. On the other hand, we show that the solutions relating to the surface elasticity model...

Electron impact fragmentation of pyrrole molecules studied by fluorescence emission spectroscopy
PublikacjaThe fluorescence emission spectroscopy using electron impact excitation technique was employed to study fragmentation processes of the gas phase pyrrole molecules. The following excited fragmentation species were observed by detection of their fluorescence decay: the atomic hydrogen H(n), n = 4-7 and the diatomic CH(A2Δ), CN(B2Σ+), NH(A3Π) and C2(d3Πg) fragments. These atomic and molecular products differ from those previously...

Landscape of the Vistula Estuary - searching for traces of ingenium embodied
PublikacjaArtykuł podaje skrótowe informacje o dawnym i współczesnym znaczeniu obiektów inżynieryjnych w krajobrazie delty Wisły, które znalazły się na trasie objazdu konserwatorskiego w dniu 5 maja w ramach realizacji programu konferencji HOT-GO 4 wraz z kalendarium ich dziejów: Most Lisewski przez Wisłę w Tczewie, wielki przekop Wisły w Świbnie, śluzy w Przegalinie, Gdańskiej Głowie i Białej Górze, relikty kanału w Piekle.

The estrogenicity of wastewater samples.
Dane BadawczeThe principle of operation of the kit is based on the fact that the tested sample with endocrine activity (containing compounds capable of binding to the human estrogen receptor α, hERα) releases the fluorescently labeled ligand (FluormoneTM ES2) from the receptor-ligand complex, which results in a reduction of the polarization value fluorescence. The...

Technical and Economic Analysis of the Supercritical Combined Gas-Steam Cycle
PublikacjaCombined cycle power plants are characterized by high efficiency, now exceeding 60%. The record-breaking power plant listed in the Guinness Book of World Records is the Nishi-Nagoya power plant commissioned in March 2018, located in Japan, and reaching the gross efficiency of 63.08%. Research and development centers, energy companies, and scientific institutions are taking various actions to increase this efficiency. Both the gas...

Web-based real-time simulation system
PublikacjaThe paper presents the development of a simulation system composed of a real-time plant simulator with real-time controller included in the software-in-the-loop structure using web-based communication. The client-server architecture build in a TCP/IP network environment was introduced, where the server is a computing unit for real-time high temporal resolution plant simulation (and optionally also as controllers' platform) and...

The rovibrational energy levels of the diatomic silver anion and neutral silver dimer
Dane BadawczeThe process of a two-channel decay of the diatomic silver anion (Ag2-), namely the spontaneous electron ejection giving Ag2 + e- and the dissociation leading to Ag- + Ag is theoretically studied. The ground state potential energy curves (PECs) of the neutral silver dimer and anionic silver diatomic molecule are calculated using the single reference...

Nowe stanowiska Dicranum viride (Dicranaceae) w północno-wschodniej Polsce na tle jego rozmieszczenia w województwie podlaskim
PublikacjaDicranum viride (Sull. & Lesq.) Lindb. is a rare moss species from the Dicranaceae family. It is strictly protected in Poland and is considered as a relic of primeval forests. The plant is also included in Annex II of the Natura 2000 Habitats Directive and Annex I of the Bern Convention. Its populations are threatened by habitat fragmentation and economic use of forest...

Human Factors and Cognitive Engineering in Functional Safety Analysis
PublikacjaHuman factors and cognitive engineering are considered nowadays as important multidisciplinary domains that focus on improving the relations between humans, technology and systems to be supervised and operated. The industrial automation and control systems (IACS) in hazardous plants are increasingly computerized and perform various safety functions. These are usually designed and implemented according to the functional safety requirements....

Labellum and gynostemium micromorphology in Polystachya (Orchidaceae)
PublikacjaPolystachya is a large, pantropical orchid genus of 200 species, most of which occur as epiphytes in sub-saharan Africa. The three-lobed labellum of most Polystachya species possesses a fleshy callus and various types of trichomes and papillae. In this paper, we present the results of micromorphological studies on the labellum of 20 species, representing eight of the 13 sections in the genus, using scanning electron microscopy...
